AbstractBackground:Rhizomelic chondrodysplasia punctata (RCDP) is a rare peroxisomal disease characterised by punctate calcifications of non-ossified cartilage epiphyseal centres. The main biochemical marker of all RCDP types is a decrease in the levels of plasmalogens. Additionally, the accumulation of phytanic acid can be used as a differential marker between types of RDCP. Due to the biochemical overlap between types 1 and 5 RCDP, a genetic analysis of these genes should be performed in patients to identify the type.Case presentation:A 2-month-19-day-old male child presented with symptoms of limited movement and discomfort with movement in the extremities. His sister, who had similar clinical findings, was diagnosed with tetralogy of Fallot and died at 6 months of age. A physical examination revealed an atypical facial appearance, bilateral cataracts, sensitivity to touch in the extremities, shortness in the proximal segments of the long bones, limited movement in both knees and elbows and axial hypotonicity. Laboratory analyses revealed normal ammonia, lactate, plasma and urine amino acids, long chain fatty acids and phytanic acid levels. Rhizomelia, significant metaphyseal expansion, irregularities in the cortex, loss of ossification, fragmented appearance and punctate calcifications in both elbows, both knees and in the femoral epiphysis were seen on the skeletal survey. A homozygote p.L70W (c.209T>G) mutation was found in theConclusions:Plasma phytanic acid levels can be normal in a patient with type 1 RCDP that develops as a result of a

We describe two brothers who presented at birth with bone growth abnormalities, followed by development of increasingly severe intellectual and physical disability, growth restriction, epilepsy, and cerebellar and brain stem atrophy, but normal ocular phenotypes. Case 1 died at 19 years of age due to chronic respiratory illnesses without a unifying diagnosis. The brother remains alive but severely disabled at 19 years of age. Whole exome sequencing identified compound heterozygous stop mutations in theperoxisome biogenesis factor 7gene in both individuals. Mutations in this gene cause rhizomelic chondrodysplasia punctata, type 1 (RCDP1). One mutation,p.Arg232∗, has only been documented once before in a Japanese family, which is of interest given these two boys are of European descent. The other mutation,p.Leu292∗, is found in approximately 50% of RCDP1 patients. These are the first cases of RCDP1 that describe the coinheritance of thep.Arg232∗andp.Leu292∗mutations and demonstrate the utility of WES in cases with unclear diagnoses.
